Spec for requesting pipeline-in-pipeline has changed new spec is:

{
    "name": "pipe_in_pipe",
    "nodes": [
        {
            "nodeName": "A",
            "input": [
                "7"
            ],
            "kind": "pipeline",
            "spec":{
                "name": "simple"
            }
        },
        {
            "nodeName": "B",
            "input": [
                "@A"
            ],
            "kind": "pipeline",
            "spec":{
                "name": "simple"
            }
        }
    ]
}

"kind": "pipeline",
            "spec":{
                "name": "simple"
            }
